If rearranging in terms of y,
3y+2x=14
Subtract 2x from both sides of equation
3y=14-2x
Divide both sides of equation by 3
Simplify 14-2x to 2(7-x) if you want to, meaning that
Answer:
speed = distance/time, so
distance = speed * time
Walking:
d = speed * time
d1 = 33 mph * x hours = 33x miles
Bicycling:
d = speed * time
d2 = 93 mph * (5 - x) hours = 93(5 - x) miles = (465 - 93x ) miles
The total distance traveled is the distance walked plus the distance bicycled
d = d1 + d2
d = 33x + 465 - 93x
d = -60x + 465
120 grams half life at 45 days would be 60 then half life of 60 in another 45 days (90 total) should be 30 grams
Answer:
X=4
Step-by-step explanation:
Subtract 5 from both sides and you get 4x=16. Divide both sides by 4 and you get x=4
